ELECTRO-en@Newoeieenneiisnneinen @PEIFICATION forming part of Letters Patent .NQ 35e-,139, dated December S-5.; Application filed August 16, 1886. Serial No. 2ll,04.0. (No model.)

To whom it may concern:

Be it known Vthat we, HENRY A. HOUSE and HENRY n. House, r., citizens ofthe United States, und residents of Bridgeport, in the county oiFnii-eld and Siate of Connecticut, have invented certain new enduseful Improvements in Electro Phonetio Telegraph Sounders,'of which the following is a specification.

Our invention is nn electro-phonetic telegraphsounder, whereby electric currents received by the instrument act upon a soundingheed to produce audible sounds, and whereby the movements oi' said heud produced oy sound fire the menus of transmitting like movements to another heed and producing audible sounds therefrom; and our invention consists in the construction of the instrument fully described accompanying drawings in whiohN Y Figure l is n longitudinal section of an insrninent embodying our invention. Fig. 2 is e sectional pien. Fi?. 3 is n perspective View showing e. modification, `the ense removed. Fig. 1i is n perspective View of the case. Fig. 5 is detached perspective View of sounding heed and bnr.

The case of the instrument consists of a nietaliic er other ringg-A, partially closed by twoA wings, between the edges 2 2 of which is :in opening, x, and two parnllelerms, 3 3, extending trom opposite pariset the ring to one sideD The ring is threaded internally, or otherwise conetrnctedjorr the attachment of a detachable sonnd-reriector, B, of rubber or other materiel, in the shnpe er"l e. ring, screwing into the ring A, sind having e Haring mouth, and between the inner end of the soundfrefleotor and an annular sent, y, on the ringr A is confined the edge efe. light diseulnr soundinghead, C, e lip, 4, on said head extending into u. notch, 5, in theA ring; A and preventing'the head from turning.

Upon one of the arms 3 is supported an electro-magnet, D, which, es shown, consists of two pole-pieces, 6 6, inserted in openings in the arm and surrounded by spools of wire, the opposite ends of the wire being connected to binding-posts 7 7, carried by the opposite arm,

The armature E' is e oar pivotedto e standtne other carrying e) liiniierssi ard, 8,\secured to one of the :mns r f longed to form 1e finger or horn, ii, tent of the vibration of the nrnietnre on its pivot in both directions defined hy n hie liniiters, end the ernietnz'e j held slightlynhove and free frein cer niet w the magnets by e. spiriti spring, passing through the tubular core 0i the outer and adjusted therein to :my desired extent h5! a. screw, 26.

The limiters 12 i5 are carried upon n her or arm, l0, secured centrally to and projectie from the sounding-heed Qend, 'is shown, limiter consists of n screw or 3 y the threaded her 1G, end.. ndji ible thereon. f

ln Figs, l and 2 the her lo is he' to i'orinv two arms, one carrying n limiter-nut, 3 2, en ranged to ineke contact with ri horn 9, uw, "i5, iiiil'iig contact with the end of the erinzitnre. in higs. 3 und 5 the her i0 is straight end enries two limiter-nuts, and passes through n 'periointion.A in the horn 9, the nuts being on moeite eides of the horn, In either euse, by girone, v' fuijusting the liinitels the amount of vii the 'armature inn-y he determined and deling` i, and in ench'case there is n direct contri-ct tween the armature. and liniiters-thet is, Aarmature itself or a positive conneetion th reni" has a. direct Contact with the lin tere. fr the magnet is charged, the ernintnre drm-,fn thereto and the horn is brought te heur the limiter l2, und when the leugnet is unchar'ged the limiter 13 prevents t" e e. swinging beyond a. verf-.f Kinn., the magnet. The limiter is conne soundingheud it er about center provided with extended contact with vthe sounding-heed, einen stiien it as it is bent by the limiter wise. NVhen the circuit vie closed and t! mature has spent its force against the hinder, and the soundinghead is held in magnetic equilibrium, audible sounds of any kind nre distinctly'received, and may also he mitted byi'putting the instrument in eircnit with another of like charset-er.
